A bandpass signal with carrier frequency 1482 Hz is a bandwidth of 154 Hz. This signal is mixed with a local oscillator output at the frequency 810 Hz, and then sampled with an ideal sampler. We is the minimum time between samples that will allow the full signal output by the mixer to be reconstructed from its samples using an appropriate low pass filter? State your answer in milliseconds to two decimal places. A bandpass signal with carrier frequency 1482...

Recall the problem from lecture iavolving an information signal betweea (-100, 100) Iz and a noise signal with positive spectrum between (500,700) Hz and negative spectrum between (-700-500) Hz. a) Suppose we want the reconstructed signal to equal the information signal. Suppose also that we would like to VIOLATE the Syquist criterion. If we can use a reconstruction ilter different than the ideal lowpass filter considered ia lecture, then find the minimum sampling frequency which violates Nyquist but still gives...
Data communication Qs A signal has a bandwidth frequency of 150 Hz and the highest frequency is 170 Hz. What is the lowest frequency of the signal? (just put the whole number. No decimal values.

An analog signal, bandlimited to 10 Hz is corrupted by high-frequency noise. The spectrum of the noise is from 30 Hz to 50 Hz. The noisy analog signal is sampled at 70 Hz. A digital lowpass filter is to be designed so as to remove the noise from the signal. For the filter design problem, what would you choose for the desired frequency response D(?)? Sketch the function for 0 ? ? ? ? where ? is normalized frequency (radians/sample)....
